Map: Near 59th Ave. & Glendale

GLENDALE, Ariz. -- Police are talking to a person of interest in a shooting that left one woman dead and put a man in the hospital Tuesday night.

It happened just after 9 p.m. in the normally quiet neighborhood of 59th and Glendale avenues.

Investigators were at the home all night, finally wrapping up their on-scene investigation at about 6 a.m., some nine hours after the shooting. They were talking to a person of interest Wednesday afternoon, but had not released any specifics.

While detectives are still piecing together the details, they do not believe this was a random incident. They believe the suspect and one of the victims knew each other.

According to police, the male victim responded to a knock at the door and came face to face with the armed suspect. They believe there was a brief exchange of words before the victim quickly shut the door.

At that point, the suspect, described only as a heavyset Hispanic male, fired at least three shots through a window.

When police arrived on the scene, they found a 36-year-old man near the front door. Once inside the house, they found a 42-year-old woman. Both had been shot.

Glendale Police Sgt. Brent Coombs said Christina Marquez died of her injuries late Tuesday night.

The male victim has not been identified, but Coombs said his injuries were not life-threatening and that he is recovering.

Officers fanned out into the neighborhood to search for the suspect, but came up empty.

Detectives have not released any suspect information, nor have they said how the suspect and the male victim were acquainted or what might have been behind the shooting.
